Why don't you call Leupold and ask them. I would assume you could but do not know for sure. I had a couple sets made and really like them. They are calibrated for a certain elevation and temp plus other factors so have them made as close to the season and temp you will be using them.Can custom dials be installed on a Leupold VXIII 3.5x10x50 Illuminated reticle 30 mm tube with finger adjustments under the caps?
